STOVEPIPE-JINT.

Specification of Letters Patent.

Patented Dec. let, i915.

Application filed March 8, 1915. Serial No. 12,876.

.from accidentally separating or from moving together or toward one another excessively, although the joint is such that a person may. readily assemble and Idetach the pipe sections.

It is also the object ort the invention toprovide a pipe joint of simple and inexpen.. sive nature, which will'eliminate the use of extraneous securing elements, outside the pipe sections themselves, and whereby the joint will be a substa-ntial one, will not be encumbering in construction, and will serve its otice in a thoroughly efficient and practical manner. l

With the foregoing and other vobjects in view which will appear as the vdescription proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that' changes in the precise embodiment of the invention herein disclosed can be madewlth- The invention is illustrated in the accompanying drawing, whereini Figure. 1 is a side elevation of the adjacent ends'oitwo stove pipe sections inseparated condition, Fig; 2 is an elevation of the pipe sections assembled. Fig. 3 isa longitudinal sectional detail taken on the line 3-3 of Figi 2. Fig. 4 is a view similar to F ig.' 3 illustrating a modification. Fig.l 5 is aview similar to Fig. l illustrating another variation. Fig. 6 is a view similar to Fig. 2, illustratingthe pipe sections of Fig. 5

assembled.

Referring to Figs. 1, 2 and-3, the coperating pipe sections are designated by the numerals l and 2,v the end oi' the section l being adapted to telescope or slip. into the end of the outer.. section 2.

tn carrying out theI invention, the innerv provided in old as well as locked together.

vithin the outwardly and beingbent back upon the section 1 is a transverse slit 3 of suitable length, and which is provided between and spaced from its ends with a curved or arcuate portion 4 projecting toward the end of forming a flexible tab 5 projecting toward the said end of the pipe section.

2 is provided with a pair of V-shaped cuts or notches 6,'p'roviding a tapered longitudi- Daily-projecting fiexible or bendable tongue 7 therebetween.

It will be evident that the interengaging portions of the pipes formed by the slit 3 and cuts 6, may be readily and inexpensively new pipe sections, so that the pipe sections In assembling the pipe sections,A they are telescoped together in the usual manner, and the tab 5 is lifted or exed outwardly in any suitable manner, so that the tongue 7 may pass under the same through the slit 3` when the pipe sections are assembled. The tab 5 will thenv overlap the basal portion of the tongue 7 upon the outer side of the pipe, while the tongue 7 will project inwardly,

and may be bent back, as clearly illustrated in Fig. 3, to prevent the pipes from accidentally separating or' becoming displaced relative to one another.` l and 2 being moved together, will cause that edge portion of the section 1 formed by the slit 3, to bind between the oblique or inclined edges of the cuts or notches 6, to limit the movement of the pipe .sections toward one another, and to assist in holding the pipe sections in position relative to one another.

The present joint will be eifective to lock `the pipe sections together, and serves its office 1n a. thoroughly efficient, simple and practical manner. To separate the pipe sectio-ns, the tongue 7 is nent/back, so that it may. be drawn out of the slit/3, when the pipe sections are separated. The tab 5 facilitates the assemblage of the parts, since provided adjacent its end, with ,j

the section, and

rl`he adja v cent or cooperating end of the other section The pipe sections may be electively f it lmay be swung or moved outwardly to receive the tongue 7 thereunder. n

Fig. -L illustrates a slight variation, since theposition of the interlocking parts is reversed.' Thus, the outer pipe section l is providedwith the slit forming the tab 5,

and the inner pipe section 2 is provided with the tongue 7', the tab 5 being disposed pipe, and the tongue 7 passing 'los outer side of the pipe, to hold the parts together. Since this is a mere reversal of the parts illustrated in Figs. l, Zand 3, further l description is not deemed necessarv.' Said,

views illustrate that the lock may be used in either manner.

Figs. 5 and t3 illustrate arother variation .in the specilic einl'iodiinent of the invention.

2a is provided with the V-shaped cuts or notches (3a forming the tongue 7&tlie same y The tab as in the iorii'is above described.

5a is flexible, the saine as the tongue 7, wherej by the tongue .7niay pass tl'irou'ghthe slit' 3 vwhenl the pipe sections are assembled.

In this` form of tlie invention, however, the" basal portion of the tongue 7iL isv providedivitha transverse open slot 8:1l extending from the lower or inner end of one of the cuts on notches 6, as clearly seen by refery ence to Fig. .5. This slot 8 isof advantage in; the assembling of the pipe sections," as will presently appear. j In assembling the pipe sections 1a and 2,

the tongue T- is slipped under the tab 5? and through the slit", but the tongue 7 need not be bent back or reflexed Within the pipe, since it is only necessary to rotate'the pipe sections relative to one, another in. the proper direction so that theporti'on ,of-'theA pipe section lEL at the respectiveedof the slit 3a will be received vbythe slot l8, toprevent the separation of the ,pipe sections, until the pipe sections are rotated back to releasing position. Y

From the foregoing, taken in connection `with the -drawing,"it is. believed that`the advantages and attributes of the invention i will br. obvious to those'faniiliar in the art, Without further comment being necessary, it being noted that the several forms of the invention have common andv characteristic features due to the general and specific structural details. i

Although the invention is illustrated and described as being employed in a stove pipe joint, it Will be understood that the securing ine-ans may be employed, for securing other pipes and other objectsofshe'et form together. j

Having thus described the invention,.

what is claimed as new'is:

A pipe joint comprising a pair of pipe section s'havin-g ends Vtelescoped together. one pipe section having a transverse Vslit adjacent its end and provided with acurved portionb'etiveen and spacedpt'rom its ends and forming a flexible tab projecting 'toward the other-pipe section, the terminals of said slit-being in alineinent and projecting beyond 'said tab in opposite directions, the last mentioned pipe section having a pair of V-.shaped cuts in its end forming a -tapered` longitudinallvprojecting tongue etitending under said tab and through said slot, lthe basal portion of said'tongue being Widerthan said vtab wherebv the edges of the tongue bind Within the terminals-of said slit' between the ends of the slit and said tab, the tongue vbeing engaged to the rst mentioned pipe section for holding the` pipe sections against separation.

In testimony that I 'claim the foregoing as my own, I have hereto .aiiixed my signature in the presence of two `ivitnesses J OHN W. SLIEMERS.
